Greetings everyone.

I need help. Just readin some articles and not find to solve my problem. I have old server Supermicro X8DT3-F. When i start to install Proxmox via ISO, i have error resolution minimum 1280x1024. Trying another modes - nothing happens. Try add nomodeset to linux kernel, again, it stuck in process. Terminal and Console only black screen.

Well, the question - can i install Proxmox VE 8.1. to this old server?

Thanks a lot for your answers.
 
Hi,
have you tried to install via the TUI option of the installer? If that does not work, you can even try to perform an installation via the serial interface (if you have the means to connect to that), which you find in the Advanced options of the installer.

Last but not least, you also have the option to install Proxmox VE on top of Debian, by following this guide https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm

Edit: fix typos

Yes, i try. But in TUI i have same problem with resolution and very disappointment because terminal and console must support old resolutions. Second try i read some solutions, i try "nomodeset" to TUI and have a black screen.

Well, the last solution try install on top of Debian?

Thanks, continue trying)
 
Same problem on 8.2
If some people encounter such a problem, why can’t the developers fix the resolution to 1024*768, so as not to have problems with this, since the interface does not support lower resolutions?

For example, I can’t install, text mode and GUI run at 640*480 resolution and there’s no way to change this...

I found a solution.
While booting from disk, press e to edit the boot and add quiet to the end of the line:
Bash: 
nomodeset video=1024x768@60

Hi, I have the same motherboard and no matter what I do it doesn't detect the usb drive with Proxmox. It says please insert bootable media. How did you flash yours and get it to work? Thanks
 
This didn't work for me the bios must not have enough memory to draw the install menu, any other ideas?
 
I FOUND A SOLUTION!

Hello everyone, good afternoon.
I'm using an old server, HP DL380 G7.
I'm accessing it through ILO and emulating the ISO.

I had the same problem.
I downloaded version 8.3.1 and it was giving me problems with the display in both graphical and "text" mode.

And the solution that worked for me was:
When loading the installation menu, I went to the "Install Proxmox VE (Terminal UI)" line and pressed the E key.
In the line that has the "vga=788" option, I changed it from 788 to 1024x768.
After that, I pressed F10 to boot with the change I made.

During boot, an error appeared, saying that the VGA 1024 mode was not recognized, but immediately afterwards, the installation in "text mode" loaded perfectly.

That's it, I hope I helped.

Im having this same issue on 8.3 and performed that fix of changing "vga=788" to "vga=1024x768" with the same result in display. It said that "vga=1024 was not support" so seems like the issue is that its not seeing the rest after the first number.
I let tried a multiply sign "*" instead of an "x", same issue. other resolutions are also a no go so far.
 
Solution:
removed the vga statement and replaced it with "nomodeset" and was able to get the no graphical option to work.
the same solution on the "graphical" option I was able to get it to load put the monitor lines are out of sync and un usable

rolled back to an earlier release and was able to get it installed (7.4)

FYI: Those numbers are all octal. I don't know if this is still true, but in the past, if you used an invalid vga option, it stated on the error message, that you should use vga=ask in order to display a list of viable options and you can try out other numbers then.

I'm a bit confused as to the GUI version (8.3) so you had to roll back to the 7.4 version and then used the nomodeset method on the GUI for the 7.4 version and it worked?

I was able to get the 8.3 version working but only the console by removing the "vga" mention and replacing it with the "nomodeset"
 
I had the same issue with an ancient HP ProLiant server. I gave up and currently install Debian from scratch.

Maybe somebody from Proxmox reads this. The Linux command line seems to be outdated. vga isn´t supported as parameter anymore.

This is how one should define the resolution now:


Code: 
setparams 'Install Proxmox VE (Terminal UI)'
  set background_color=black
  set gfxpayload=1024x768x16
  echo 'Loading Proxmox VE Console Installer ...'
  linux /boot/linux26 ro ramdisk_size=16777216 ru quiet splash=silent proxtui
  echo 'Loading initial ramdisk ...'
  initrd /boot/initrd.img
